WINDOW-SCREEN.

Specification of Letters Patent.

' Patented Ju1y 2, 1907.

Application filed March 19,1907- Serial'No. 363,268.

To all whom it may concer'm.

Be it known that I, SAMUEL EDGAR SNnnnKER, a citizen of the UnitedStates, and a resident of White Plains, in the county of Westchester andState of New York, have invented a new and Improved Window- Screen, ofwhich the following is a full, clear, and exact description. i

This invention relates to window screens, and is particularly useful inconnection with devices of this character in which the screen, intendedto prevent the entry of insects, dust and the like through the window,is adjustable.

The. object of the invention is to provide a simple, strongand durablewindow screen, in which the screen is supported upon a roll and in whichthe screen may be adjusted and secured in position as desired.

The inventionconsists in the construction and combination of parts to bemore particularly described hereinafter and fully set forth in theclaims.

' Reference is to be had tothe accompanying drawings forming a part ofthis specification, in which like characters of reference: indicatecorresponding parts in all the views.

Figure 1 represents a window screen frame showing my device appliedthereto; Fig. 2 is a side elevation of the window screen; Fig. 3 is avertical cross-section .of the device; and Fig. 4 is an enlargedhorizontal section of a detail.

Referring more particularly to the drawings, I provide a supportingframe 2 which is adapted to be fixed in position in a window-frame 1 ofthe usual construction, as shown most clearly in Fig. 1. The supportingpose. The weights 8 are arranged to slide upon ver ticalguides 1Oconsistingof rods of metal or other suitable material vertically mountedupon the lateral. members of the supporting frame 2. The arrangement issuch that if the weights 8 slide downward upon the guides 10*the cords 7are unwound from the drums, thereby rotating the roll 4 and thus windingup the screen upon the roll. When the screen is unrolled from the roll4' the weights are moved upwardly upon the guides. The free end of thescreen 5 is provided with a cross-piece 11 for a purpose which willappear hereinafter.

I provide a holding frame 12 adjustable with respect to the supportingframe in a direction substantially perpendicular therewith. The holdingframe comprises lateral members and a cross member joining the upperextremities of the lateral members. Brackets 13 are rigidly mounted uponthe lateral members of the supporting frame adjacent to the lateralmembers of the holding frame, by means of laterally disposed toes l4"securedin position by means of screws or bolts 15. The brackets 13extend outwardly beyond the holding frame and at their outer extremitieshave slots 16 within which are slidably located the laterally disposedends -18 of levers 17. The extremity of the end 18 of each lever 17 issecured to a holder 19 rigidly mounted upon a lateral member of theholding frame. The opposite end 20 of each lever 17 is bent and ispivotally secured to a rod 21 substantially parallel to the lateralmembers of the holding frame. The rods 21 are movable in asubstantially. vertical direction and are pivotally connected with theholding frame at their upper and lower extremities by the levers 17. Thearrangement is such that the upward or downward movement of a rod 21 istranslated through the levers 17, the ends 18 of which are forced tomove in a direction substantially perpendicular to the movement of therod 21 by means of the slots 18, to a movement of the holding framesubstantially perpendicular to the movement of the rod. It will beunderstood that as the rods 21 are moved up or down the holding frame 12is correspondingly moved toward the supporting frame or away from thelatter. The brackets 13 are provided with guides 22 within which therods 21 are slidably located.

Near the lower extremities of the lateral members of the supportingframe are brackets 23 at which bell cranks 2,4 are, pivotally mounted.One arm 25 of each bell crank 24 is provided with a fork engaging withan arm 26 extending laterally from each of the rods 21. The other armsof the bell cranks 24 are connected by a hand bar 27 by means of whichthe bell cranks'may be manually operated to raise or lower the rods2-l.

Whenit is desired to place the screen in position over the windowopening, the hand bar 27 is raised, thereby raising the bars 21 andmoving the holding frame outwardly from contact with the' supportingframe; the screen is then un olled from \the roll 4 and is -drawndownward until the cross piece 11 rests against the window-sill. Thehand bar is then depressed,

. whereby the holding frame is forced against the supporting frame andthus securely clamps the screen in position. The lateral members of'theholding frame do notextend to the window-sill but the arrangement issuch that the cross piece 11 engages with the lower extremities of thelateral members of the holding frame whereby the screen is preventedfrom being accidentally displaced to permit its being rolled upon theroller through the action of the weights 8. It will be understood thatwhen it is desired to remove the screenfrom g i seem? the window it ismerely necessary to raise the hand bar of the bell cranks to release theholding frame,

, whereupon the weights 8 slide downwardly upon the guides 10 and returnthe screen to its inoperative rolled-up position upon the roll 4.

Having thus described my invention I claim as new and desire to secureby Letters Patent 1. A window screen, comprising a supporting frameadapted to iii: in a window, a holding frame adjustable with respect tosaid supporting frame, a member arranged to slide upon said supportingframe, a lever secured to said member and said holding frame, means forcontrolling said lever whereby the movement thereof effects a movementof said holding frame, at an angle with the said supporting frame, and ascreen adapted to be removahly insertedbetween said frames.

2. A window screen, comprising a supporting frame adapted to fit 'in awindow, a holding frame adjustable with respect to said supportingframe, a member arranged to slide upon said supporting frame, a leversecured to said member and to said holding frame, means rigid with saidsupporting frame for controlling said lever whereby the movement thereofeffects a movement of said holding frame at substantially right-angleswith said supporting frame, and a screen adapted to be removablyinserted be tween said frames.

3. A window screen,v comprising a supporting frame adapted to fit in awindow, a holding frame adjustable with respect to said supportingframe, a slidable member carried by said supporting frame, a bracketrigid with said supporting frame, a lever secured to said member and tosaid holding frame and controlled by said bracket, and a screen adaptedto be removably inserted between said frames.
